Upper Darby has more brick row houses per square mile than almost anywhere else in Delaware County. That’s not a fun fact it’s a maintenance reality. When mortar joints crack on a home that’s pushing 90 years old, water doesn’t wait. It gets in, it freezes, it expands, and by spring you’ve got loose bricks, a damaged stoop, and a problem that costs three times more to fix than it would have a year ago.
Delaware County averages over 90 freeze-thaw cycles a year. For the kind of older brick construction that defines Upper Darby’s neighborhoods from Drexel Hill’s semi-detached homes to the denser row houses near the 69th Street corridor that’s 90 chances per winter for water to do damage through every crack you haven’t addressed. Good masonry work stops that cycle before it compounds.
Beyond repair, there’s real value in what new hardscaping does for a property in Upper Darby. A properly installed stone patio, a concrete curbing system around your garden beds, or a retaining wall with drainage built in these aren’t luxury additions. In a township where lots run smaller and stormwater is a documented challenge across the Darby and Cobbs Creek Watershed, they’re practical investments that protect your yard, your foundation, and your property value for years.
We’ve been doing masonry and hardscaping work in Delaware County for over 15 years, and Upper Darby has been a core part of that work. We’ve worked on the same kind of older brick construction that makes up most of Upper Darby homes built before 1939, row houses with lime-based mortars, stoops that have seen decades of Pennsylvania winters. We know what these structures need, and we know what happens when a contractor gets it wrong.
Every project runs with one crew the same team from the first day of prep through the final cleanup. No subcontractors showing up mid-project, no handoffs, no “that wasn’t our part.” When you call with a question, you reach someone who was actually on your job. That’s not common in this industry. It should be, but it isn’t.
We’re based in Aston, right here in Delaware County. Upper Darby is part of the same county we’ve worked in for a decade and a half we know the permit process, we know the housing stock, and we know what the ground looks like after a hard winter in this watershed.
It starts with a straightforward site visit. We look at what you’ve got whether that’s a crumbling stoop on a Drexel Hill semi-detached, a retaining wall that’s starting to lean, or a backyard that needs a patio and proper drainage and we give you a clear scope and a real number. No vague estimates that balloon later.
From there, we handle the permit side if your project requires it. In Upper Darby, retaining walls under four feet need a fence permit, and anything over four feet requires a full building permit through the township. New patios and full driveway replacements require permits too. If your property sits in a floodplain zone near one of the five creeks that run through the township, there’s an additional floodplain development permit involved. We know this process we’ve done it and we don’t leave it on you to figure out.
Once permits are in order and a start date is confirmed, that date is real. You’ll get a written timeline with your proposal. We show up when we say we will, we work clean in tight residential settings, and we don’t disappear when the job is done. If something comes up after the project is complete, you’re not calling a number that goes to voicemail.

Masonry work in Upper Darby isn’t one-size-fits-all. The needs here are different from a newer subdivision in Chadds Ford or a large-lot property in Radnor. Lots are smaller, homes are older, and the housing type primarily attached and semi-detached brick construction demands a contractor who selects the right materials for the job, not just whatever’s easiest to install.
For repair work, that means matching mortar strength to the existing brick. Older brick is softer than modern materials, and using a high-Portland mortar mix on an 80-year-old row house will cause the brick itself to crack before the mortar ever fails. We use lime-compatible mixes where the existing construction calls for it. That’s not a detail most homeowners would know to ask about but it’s the difference between a repair that lasts and one that makes things worse.
For new installations stone patios, brick walkways, retaining walls, concrete curbing, decorative gravel every project starts with proper base preparation and drainage planning. In a township that sits within the Darby and Cobbs Creek Watershed, drainage isn’t optional. We also install concrete curbing for garden bed definition and decorative gravel for low-maintenance landscaping, both of which are practical solutions for Upper Darby’s smaller lot sizes. Whatever the scope, the work is done by one crew, to one standard, from start to finish.
It depends on the scope of the work, but Upper Darby does have specific requirements worth knowing before you start. Retaining walls under four feet in height require a fence permit. Anything over four feet requires a full building permit. New patios and site improvements require permits, and if you’re fully removing and replacing a sidewalk or driveway even at the same size that also requires a permit. Repaving over an existing surface without increasing its size is generally exempt.
There’s also a zoning step that comes before the building permit in Upper Darby, which affects your timeline if you’re not expecting it. And if your property falls within a floodplain zone near Darby Creek, Cobbs Creek, or one of the other waterways in the township, you’ll need an additional Floodplain Development Permit under Chapter 305 of Upper Darby’s ordinance. We handle the permit process as part of the project so you’re not navigating the township’s Buildings Department on your own.
For most residential repair jobs in Upper Darby repointing cracked mortar joints, repairing a damaged stoop, addressing loose bricks you’re typically looking at somewhere between $500 and $2,500 depending on the extent of the damage and how much of the surface needs attention. Larger structural repairs or full stoop replacements will run higher.
The more important cost conversation is what deferred repair actually costs. Upper Darby’s housing stock is old over 40% of homes were built before 1939 and older brick construction is more vulnerable to water infiltration through failing mortar joints. With 90+ freeze-thaw cycles every winter in Delaware County, a small crack in the pointing becomes a structural problem faster than most homeowners expect. Catching it early is almost always the cheaper path. We’ll give you a straight assessment of what needs to happen now versus what can wait, so you’re making a real decision, not a pressured one.
This is one of the most important questions in masonry repair, and it’s one that a lot of contractors get wrong. Older brick the kind found in the pre-1939 row houses and attached homes that make up a significant portion of Upper Darby’s housing stock was manufactured to be softer and more porous than modern brick. It was designed to work with lime-based mortars that have some flexibility and allow moisture to escape through the joint rather than through the brick itself.
If a contractor uses a high-Portland cement mortar on older brick, the mortar becomes harder than the brick surrounding it. When the wall moves and all walls move slightly with temperature changes and settlement the stress goes into the brick rather than the mortar joint. That causes spalling and cracking in the brick face, which is far more expensive to repair than a failed mortar joint. The right approach is a lime-compatible mortar mix matched to the age and type of brick on your specific home. We assess this before we mix anything.
Upper Darby sits within the Darby and Cobbs Creek Watershed, a 77-square-mile drainage basin that the Delaware County Conservation District has identified as having documented flooding and stormwater challenges due to overdevelopment. Five creeks run through or border the township Darby Creek, Cobbs Creek, Naylor’s Run, Munkinipates Creek, and Collenbrook Creek. The township has a formal stormwater management program as a result.
What this means for retaining walls is straightforward: drainage isn’t a detail you can skip. A retaining wall built without proper drainage behind it will have hydrostatic pressure building against it every time it rains heavily or snow melts. In Upper Darby’s environment, that pressure is significant and recurring. We design drainage into every retaining wall we build gravel backfill, weep holes, and proper grading so the wall does its job for decades instead of failing within a few years. If your property is near one of the township’s creek corridors, we’ll also flag whether a floodplain permit applies to your project before we start.
Spring and fall are the two windows that most Upper Darby homeowners are working with. After a Delaware County winter, the freeze-thaw damage becomes visible cracked pointing, heaved pavers, settled stoops and spring is when most people call. That’s also when reputable masonry contractors book up fastest. If you’re calling in April hoping to start in April, you’ll likely be looking at June or July for a quality contractor.
Fall is the second surge homeowners want projects done before the next winter hits, and for good reason. Unrepaired masonry heading into another round of freeze-thaw cycles gets worse, not better. The practical advice is to plan early: get your estimate in late winter or early spring, lock in a start date, and you’ll be ahead of the rush. Masonry work can’t be done below about 40°F without special precautions, so January and February are planning months in this area, not installation months.
Upper Darby’s density means a lot of properties have smaller front yards, narrow side yards, and limited backyard space compared to townships like Radnor or Springfield. That doesn’t mean masonry work isn’t worth doing it just means the scope looks different. Concrete curbing is one of the most practical investments on a smaller lot. It defines garden bed edges cleanly, prevents mulch from washing into the lawn or onto the sidewalk, controls water flow across the surface, and reduces the maintenance work that comes with undefined borders. It works on a tight Upper Darby lot just as well as it does on a larger suburban property.
Decorative gravel with proper weed barrier and edging is another option that works well in Upper Darby particularly for front yards or side yards where maintaining a full lawn isn’t realistic. For homeowners with enough backyard space, a stone patio or brick walkway adds real usability and value. We’ll look at what you’re working with and give you an honest read on what makes sense for your specific property not just what’s most expensive.
